BANDREJECT (NOTCH) FILTERS


API’s reputation for designing and delivering some of today’s most challenging Bandreject filters is the reason why engineers trust us with their designs. Choosing from a wide assortment of topologies, including lumped element, cavity, ceramic, waveguide and suspended substrate, our engineers match the optimum topology to your requirements.

Unlike one dimensional filter companies, SMI continues to prove that by offering multiple options, a customer can weigh the benefits of: size vs. loss, rejection vs. size, selectivity vs. group delay...and select the best filter to optimize system performance.
